APPARATUS FQR ORNAMENTING HOLLOW METALLIC ARTICLES.

SPECIFICATION forming part of Letters Patent No. 249,132, dated November 1, 1881. Application filed June 13, 1881. (No model.)

To all whom it may concern:

Be it known that I, LE ROY S. WHITE, of WVaterbur-y, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Apparatus for Ornamenting Hollow Articles of Metal, of which the following is a specification.

My invention relates, chiefly, to the method of ornamentin ghollow articles by placing them, filled with liquid, in an engraved die and subjecting the liquid to a blow by a plunger carried by a hammer or drop of a drop-press. In order to permit the removal of the ornamented article, the die should be sectional and fit within a die-block, from which it is raised to permit the sections of the die to separate.

The invention consists in a novel means of raising said die by liftingbars, which are acted on and raised by the hammer or drop in its upward movement, and serve to raise the sectional die.

In the accompanying drawings, Figure 1 represents an article of the kind to be produced. Fig. 2 represents a vertical section of a machine for making said article, and Fig. 3 represents a transverse section thereof upon the dotted line 00 m, Fig. 2; and Fig. 4 represents, upon a larger scale, a plan of the die employed.

Similar letters of reference designate corresponding parts in all the figures.

In Fig. 1 I have represented an article, A, which may be produced by my machine, and which is a butt-tip for a whip, having its lower end closed, and ornamented by having its interior indented or forced outward to form protuberances or projections e on its exterior, and also a projecting bead, a.

I will now describe the machine which I employ to produce ornamented articles.

The bed of the machine is composed of upper and lower portions, B B, having between them an opening or cavity, 0, the purpose of which will be hereinafter explained.

Secured rigidly to and projecting upward from opposite sides of the bed or base B B are upright guides D, having in their inner sides or faces V-shaped ways 6, in which is fitted a drop or hammer, E, which may be raised by any suitable mechanism commonly used in drop-presses, and released when in an elevated The drop said die is engraved or out so as to form the ornamentations a a .on said article. As clearly shown in Fig. 1, which shows the article full size, the sides thereof taper upward, and hence it is obvious that in order to enable the article to be removed from the die after being ornamented it is necessary to make said die in sections, as shown in Fig. 4. The die there shown is composed of four separable pieces, 0, which give form to the sides of the article A, and are inclined outward from their upper end downward to correspond to the taper thereof, and a fifth piece, 6, which supports and gives form to the end of said article. The cavity (1 in the die block or holder F flares upward, as clearly seen in Fig. 2; and as the exterior of the diesections 0 are correspondingly flared, it will be obvious that if the bottom section, a, of the die be pushed upward it will raise the sections 0 into a wider part of the cavity (1, and permit them to be separated sufficiently to withdraw the ornamented article A. The mechanism for thus elevating the die forms the only feature of novelty in the machine, and will now be described.

Arranged in the cavity 0 between the upper and lower parts, B B, of the bed is a crossbar, G, the ends of which project into the uprights D, and are capable of a slight vertical movement therein; and f designates a pin or plunger resting upon the cross-bar G and projectiug upward through a hole or guide in the upper part, B, of the bed and in the die-holder F. The upper end of the pin or plunger f is immediately below the bottom piece, e, of the die, and it will be readily understood that if the cross-bar G and pin f be raised they will raise the sections 0 e of the die, and permit the ornamented article A to be removed from the die.

In the bottom of the V-shaped ways I) in the IOC guides D are grooves g, in which are fitted upright lifting-bars H, which are adapted to move vertically in said grooves, and at their upper ends said bars H have projections, gibs, or heads 7:, which project inward over the hammer E. At their lower ends the bars H have corresponding projections or heads 1?, which project inward under the cross-bar G. It is therefore obvious that it, when the drop or hammer E moves up it strikes the projections or heads h, it will lift the bars H, and their projections or heads i, acting upon the under side of the cross-bar G, will lift the latter and with it the pin or plungerf, and the bottom section, 0, of the die, through which the sections 0 ol' the die will be lifted.

In the operation of my machine the article to he ornamented is placed in the sectional die 0 e and filled with water or other liquid. The hammer or drop E is then released, and as it descends its plunger IE will enter the open end of the article and will thus strike a violent blow on the water or liquid contained therein. The said plunger should fit the open end of the article sufficiently tight to prevent the water or other liquid from escaping too rapidly, and if so made it is clear that the striking force of the hammer or drop is transmitted with tremendous force through the liquid, and acts equally on the parts of the interior of the article, thus forcing it outward until it accurately and wholly fills every depression in the die, even though they be minute. When the drop or hammer is raised it raises the bars H, as before described, and thus lifts the sectional die and releases the finished article.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for ornamenting hollow metal articles, the combination, with the sectional die and hammer or drop, of the lifting-bars gibbed or having projections above said hammer or drop, so as to be raised by the latter LE ROY S. WHITE.
